LAWRENCE L. MORRIS, OF BALLSTON SPA, NEW YORK.

PAPER-MAKING MACHINE.

Specification of Letters Patent.

Application filed January 29, 1920. Serial No. 354,948.

To aZZ whom it may concern:

Be it known that I, LAWRENCE L. Monms a citizen of the United States, residing at Bailston Spa, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Paper- Making Machines, of which the following is a specification.

My invention relates to machines for making paper and the objects of my invent1on are to provide a paper making machine on which can be made a wide variety of papers, varying in thickness from thin tissue to straw wrappers, which will not require the use of Web carriers of either wire or felt, and which will also crimp the thinner papers if so desired.

accomplish these objects by means of the machine illustrated in the drawing which is a side elevation of my machine, partly in section, and also shows a portion of a calender machine.

Referring to the drawin A, represents the frame of the machine, represents the tank which is of the usual form and construction, and rovidedwith a stock inlet F. and a flow-0 B Mounted in the frame of the machine and projecting into the tank B, in the usual manner, is the web-forming rotating suction cylinder C, which may be of any desired typg or construction.

ounted above the suction cylinder 0, at or near the point where the suction is released, I mount a jacket-roll D, provided With a guard board E. Suitably mounted in the tank B. is a dandy roll Y.

In the frame A. I mount the suction rolls J, N and Q. Above the suction rolls J, and N, respectively, I mount the rollers K and 0, adapted to rest upon the suction rolls or upon the web or aper assing over said suction rolls. M, and U, are guide rolls one of which is mounted beside each of the before mentioned suction rolls.

Above the suction roll Q. I mount the couch roll R, provided with a uard board S.

Adjoining the couch roll I mount a hot press roll T, adapted to press against the couch roll; and adjacent to said hot press roll I mount a doctor Z, adapted to be adjusted so that paper after it passes over the hot press roll T. will drag over the edge thereof and be crimped thereby.

I preferably mount between the suction cylinder C. and the suction roll J. the brush the doctor.

roll G, with a suitable guard H, said brush adapted to clean the foraminated cover of the suction cylinder.

Suitable sprinkling pipes s. are also pro-- vided to clean the surface of the Various suction rolls.

The usual means for driving the rotating parts of the machine, and the customary suction and water pipes, are, of course, providedthough none of them are shown.

The operation of my machine is as follows: Stock is forced through the pipe F. into the lower chamber of the tank B. and flows, as indicated by the direction darts, into contact with the web-forming suction cylinder 0. The excess flow of stock escapes through the flow-off B The dandy roll Y. smooths out and slightly compacts the web X, which has been formed on the surface of the suction cylinder C. The web X. then passes under the jacket roll D, which further compacts the web, squeezes out a portion of the water contained therein, and picks it off of the web-forming cylinder.

The web then passes over the suction roll J, under the guide roll M, over the suction roll N, under the guide roll P. It then passes between the suction roll Q. and the couch roll R, under the guide roll U, between the couch roll R. and the hot press .roll T. and then to the press set of the calender machine.

If it is desired to crimp the paper, the doctor Z. is adjusted so that in passing from the hot press roll T. to the calender press set, the webX. is caused to drag over the edge of This dragging will cause the desired crimp.

In running some of the heavier papers, such as straw wrappers, it is unnecessary to run the web over the hot press roll T, and

in such cases the web X, after it passes the rotating web-forming suction cylinder mounted in said tank; a jacket roll mounted above and adapted to co-act with said suction cylinder; a series of suction rolls mounted in said frame; a couch roll mounted above and adapted to co-act with the suction roll at the end of said series farthest from said suction cylinder; idler rolls mounted above and adapted to co-act with the remainder of said series; and guide rolls, one following each of said suction rolls.

2. In a paper making machine, a frame;

a tank adapted to contain paper pulp; a rotating web-forming suction cylinder mounted in said tank; a jacket roll mounted above and adapted to co-act' with said suction cylinder near the point where the suction releases; a dandy roll mounted adjacent to said suction cylinder; a series of suction rolls mounted in said frame; a couch rollmounted above and adapted to co-act with the'end roll of said series farthest from said suction cylinder; idler rolls mounted above and adapted to co-act with the remainder of said series; a guide roll following each of said suction rolls; guard boards, mounted over said jacket roll and said couch roll.

3. In a paper making machine, a frame; a tank adapted to contain paper pulp; a rotating web-forming suction cylinder mounted in saidtank; a acket roll mounted above and adapted 'to' co-act with said suction cylinder; a series of suction rolls mounted in said frame; idler rolls mounted above and adapted to co-act with each of said series, except the one farthest from said suction cylinder; a couch roll mounted above and adapted to co-act with the suction roll before excepted; guide rolls, one following each of said suction rolls; a hot press roll mounted adjacent to and adapted to co-act with said
